As we know, there are advantages , and disadvantages with everything . The invention of the calculator had brought advantage to us .However，a survey by the expert shows that the calculating ability of teenagers in schools has obviously decreased compared with that of those ten years ago . That’s true. In our school life, we tend to calculate things with calculators more and work our mind less . As a result , we become low in calculating or even can‘t calculate well ,esp in the tests., which upsets us a lot. As far as I am concerned , as school students , we are old enough to make right decisions by ourselves . It’ s important to learn to change ourselves and form a good habit to improve ourselves. We must work our mind as much as we can , and I’m sure constant calculating in mind will train our quick response . So in our opinion , we school students had better seldom or not use calculators .
